CHARLES DENNIS'ION BURN EY, OF KILMESTON, ALVESFORD, ENGLAND.

AERONAUTIGAL APPARATUR Specification of Letters Patent.

Patented Aug. 26, 1913.

Application filed January 25, 1913. Serial No. 744,17

To all whom it may concern:

Be it known that I, CHARLES DENNIsToN BURNEY, a subject of the King of Great Britain and Ireland, residing at Dean 'Holme, Kilmeston, Alvesford, in the county of Hants, England, have invented new and useful Improvements in and in Connection with Aeronautical Apparatus, of which the following is a specification.

This invention relates to improvements in aeronautical apparatus and has for its object to enable the same to alight upon or ascend from water with increased safety and reliability, while at the same time obviating the risk of pique or pitching which is involved when, in' alighting, the lower part of the apparatus is abruptly retarded owing to its becoming immersed,

In the specification which accompanied my Patent Application Ser. N 0. 736,836 filed on the 14th December, 1912, is described a hydro-aeronautical machine wherein the fuselage consists of a water-tight boat-like structure I beneath which are arranged 'hydropeds furnished with numerous hydroplanes, the latter being arranged in step formation; that is to say, in superposed horizontal planes.

In the accompanying' drawings Figure 1 is a side elevation, Fig.2 a front elevation,

and Fig. 3 is a broken plan view of ahy dro-aeronautical machine embodying my" present improvements, As will be seen, the

hydropeols A are arranged obliquely with considerable lateral rake, with the eflect that the lifting force, produced by the hydro planes 0. carried by either of the hydropeds, is transmitted directly to the fuselage or body portion B, through the hydroped concerned. The hydropeds A are, however, utilized to furnish low points of attachment for the under-ties 0, whereby the wings of an apparatus of the heavier-thanair type are held against upward collapse. By providing such low points of attachment for the said under-ties, the employment of supporting surfaces of increased span is rendered practicable, with a consequent gain in the efficiency of the apparatus. The said hydropeds are also connected together by,

trol' levers or wheels.

means of cross-ties a andthus afford one another mutual support.

Adjacent to the lowermost hydroplanes are arranged .one or more propellers D, adapted for use in water and capable of being driven from the main engine employed for driving the aerial propeller. As the apparatus, under the influence of the propellers D or the aerial propeller or pro--- pellers or of both sets collectively, gather speed, it rises by degrees and finally its whole weight becomes transferred from the 'liydroplanes to the aeroplanes, as the machine is launched in flight. 'Before again alighting upon water, the water-propellers I) are set in motion with the eifect that the lower portion of the apparatus is maintained well in advance and the risk of pique is obviated;

. In a machine of the character herein referred to, it has been found that, if the wing-warping control-connections be led by way of the hydropeds, so that they are immersed in water, they occasion considerable head-resistance, and aremoreover liable to injury from contact with floating bodies.

In Fig. 3' is illustrated in plan my improved method of efl'ectin'g the wing-warping and of arranging the control-connections, whereby these disadvantages are obviated.

Upon the wing H is mounted a longitudinal overhead spar 72. supported upon converging struts and ties 71. which are suitably trussed. Toone or more points in the overhead spar are connected the wing-warping control-connections k which are then led rearwardly in relation to the machine,

inwardly through the after portion of the fuselage B andforwardly to the usual con- The overhead spar it may be connected with its struts and ties h, and through them with the wing H, in such a manner as to permit of the structure, when notin use, being collapsed or folded together.

When it is desired to warp one of the 1 wings, a rearward pull 'is' transmitted throughthe control-connections to the over-. head spar pertaining to that wing and exerts a torsional efi'ect on -the latter.

I claim control lever or wheel to the warping spar In a hydro aeronautical machine, the and'arranged entirely above the Water level.

herein described means for use in warpm f the supporting surfaces or wings, sami a QHARLES DENNISTON BURNEY' 5 comprising a longitudinal warping spar, Witnesses:
